'Things like these may get you into trouble': Koeman advice Pique on referee comments
Gerard Pique has suggested that most referees in Spain are biased as they support Real Madrid.
Ronald Koeman says Pique is responsible for what he says.
However, he should be very careful, Koeman adds.
"Gerard [Pique] is responsible for what he says, but one has to watch out because little things like these may get you into trouble," Ronald Koeman has told the media when asked about Pique's controversial comments on refereeing in Spain.
As a reminder, the Spanish FA's Competition Committee have opened an investigation against Pique after the centre-back suggested that the majority of referees in La Liga support Real Madrid.
